LXOM-AT OSCILLATOR
500 kHz to 120 MHz
Low Power Crystal Oscillator
™
DESCRIPTION
The LXOM-AT consists of a TTL and CMOS-compatible
hybrid circuit and a miniature quartz crystal packaged in a
hermetically-sealed metal DIP. Permanent, precision tuning
and a hermetically sealed AT quartz crystal allows for very tight
calibration tolerance and eliminates the need for a tuning
capacitor, a major source of long-term frequency drift.

ENABLE VS. TRI-STATE
Enable: When pin 1 is low (0), the oscillator stops
oscillation.
Tri-state: When pin 1 is low, the oscillator is running.
However, the output buffer amplifier stops
functioning and output is in high impedance
(Z) state.
